[2005] emailing problems

[Big Red]

Hi, I have some emailing code in my web application. It has been working and now I have to change it because I kept getting the error of the email not being able to relay or something like that. I got my code to work after I changed it, so I changed ALL my email code in the entire program. Now all of a sudden it's not working. It worked just a minute ago, and now it's not. Here's my code:

Dim msg As String = "Another test. Thank You!" 
               Dim emp_email As String 
        emp_email = "[email protected]" 

 Dim message As New System.Net.Mail.MailMessage("[email protected]", emp_email, "test", msg) 
        message.IsBodyHtml = True 

        Dim emailClient As New SmtpClient("dwmail1") 
        emailClient.Host = "dwmail1" 
        'Dim SMTPUserInfo As New System.Net.NetworkCredential("mrequester", "schedule", "DWLAN") 

        emailClient.UseDefaultCredentials = False 
        emailClient.Credentials = New Net.NetworkCredential("athorson", "feeco") 
        emailClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis 

        Try 
            emailClient.Send(message) 
        Catch ex As Exception 
            MsgBox(ex.ToString) 
        End Try

I'm really stumped because it just worked and it's not giving me an error or anything. can anyone help me? Thanks!

My guess is because you aren't pointing to the right SMTP Host. dwmail1 should probably be something like smtp.dwmail1.com maybe? If that doesn't work, I would try some different delivery methods.
